Specification of Letters Patent.

Patented July 28, 1914.

Application filed February 13, 1914. Serial No. 818,573.

To all whom it may concern Be it known that I, Cnannus D. Unsure, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in renches; and I do hereby declare the following to be a full, clear, and evact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wrenches and has for an object to provide a combination of quick acting and screw adjusting wrench.

A further object of the invention is to provide improved means for actuating the movable jaw and with improved means for reducing the friction of such jaw in its movement.

With these and other objects in View the invention comprises certain novel construetions, combinations and arrangement of parts as will be hereinafter more fully dcscribed and claimed.

In the drawings: Figure l is a view of one embodiment of the wrench in side elevation. Fig. 2 is a view of the wrench in edge elevation. Fig. 3 is a view of the wrench with the rigid jaw in side elevation and the movable jaw in section. F 4 is a transverse sectional view of the wrench taken on line 4i-4i of Fig. 3.

Like characters of reference designate corresponding parts throughout the several views.

The improved wrench which forms the subject matter of this application comprises a rigid jaw member integral with the handle member 11. in substantially the usual and ordinary manner and provided with the customary rack 12 extending along one edge. Upon the handle and over the rack 12 a movable jaw 13 is mounted controlled by a knurled worm let engaging the rack 12. The knurled worm 14: is j onrnaled upon the movable jaw 13 in any usual and ordinary manner as by the employment of a pintle 15 having a reduced neck 16 and held in position by a pin 17. The knurled worm and its manner of mounting is, however, not pecular to the )resent invention and forms no part thereot.

The opening through which the handle member 11 extends is made wider than ordinary and at the side opposite the knurled worm let provides a considerable space as indicated at 18. The space thus provided permits a limited angular movement of the pivoted jaw 13 about the points 19 and 20 to the extent that the knurled worm 14 may be moved out of engagement with the rack 12 and permit the sliding jaw to move freely without the restraint of such engagement. To hold the knurled worm 1 L normally in engagement with the rack an index pin 21 is provided having a head within the chamber 18 slidable upon the handle member 11 rounded to reduce friction. A spring 22 surrounds the pin 21 and is seated, in a socket 23 formed in the wall of the chamber 18 so that such spring 22 and the head of the pin 21 may be seated largely if not entirely within such socket. I t is obvious, therefore, that when manual pressure is exerted upon the rear end of the movable aw member the jaw will be moved against the tension of the spring 22 to clear the knurled worm 14; from engagement with the rack 12 so that said jaw member may be freely moved along the handle. To provide for such manual ongagement and n'lovement of the jaw a knurled shoulder 24 is provided at such ongaging point.

lo taclhtate the movement of the aw along the handle member a socket 25 is produced in the forward end of the movable jaw 13 adjacent the point 19 as shown more particularly at Fig. 3. lVithin this socket 25 a spring 26 is inserted and a ball 27 mounted upon the end of the spring in engagement with the handle member upon the side opposite the pin 21.. The particular object of this ball and spring arrangement is to add ease to the movement of the jaw along the handle member more particularly when the movable jaw has been moved so that the point 19 is in engagement with the rack 12. The ball 27 in such case prevents the corner or point 19 from engaging in such gagement with the rack; a ball carried by rack and preventing the movement of the the movable jaw; and a spring arranged'to hold the ball in yielding engagement with I claim: the rack side of the handle member.
